Removing the hot-swap hard disk drive backplane

To remove the hot-swap backplane on the 5U server model with hot-swap power supplies, complete the following steps.

1. Read the safety information in Safety and Installation guidelines.
2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
3. Unlock and remove the side cover (see Removing the side cover).
4. Remove the lower bezel (see Removing the lower bezel).
5. Remove the hot-swap SAS/SATA hard disk drives installed in the hard disk drive cage (see Removing a hot-swap hard disk drive).
6. Carefully turn the server on its side so that it is lying flat, with the system board facing up.
   Attention

   Do not allow the server to fall over.
7. Remove the hard disk drive fan duct (see Removing the hard disk drive fan duct). Doing so requires removing the cables from the cable clips.
8. Press and hold the hard disk drive cage release tab; then, rotate the hard disk drive cage out of the chassis until the retaining tab on top of the cage locks into place.
